The role of motivation in the intention of nurse clinical instructors to persevere in their role: A cross-sectional study

AimTo examine factors related to clinical instructors’ motivation to persevere in their role, such as motivation, benefits and support.BackgroundClinical nursing education is mainly based on acquiring hands-on training provided by clinical instructors in various health environments. In recent years the number of nursing students in Israel has increased, resulting in a shortage of clinical instructors. One of the reasons is that many clinical instructors do not persevere in their role for long.DesignA quantitative cross-sectional study.MethodsParticipants included 176 licensed clinical instructors. Data were collected between January 2020 and March 2020 using an online questionnaire. The questionnaire included five parts: personal details, job benefits, perceived support, motivation for serving as a clinical instructor (autonomous motivation, controlled motivation and amotivation) and the intention to persevere as a clinical instructor.ResultsFindings showed clinical instructors’ intention to persevere in their role was positively associated with the overall score for motivation, perceived support and job benefits and negatively associated with amotivation (defined as a state where people do not intend to perform a particular behavior or do not know why they are performing it). Two mediation models analyses indicated that autonomous motivation fully mediates the relationship between support and the intention to persevere as a clinical instructor and that amotivation partially mediates the relationship between job benefits and the intention to persevere as a clinical instructor. The findings also demonstrated a correlation between the nature of the benefits preferred by clinical instructors and their motivation to persevere in their role.ConclusionsMotivation plays an important role in the intentions of clinical instructors to persevere in their role. Providing clinical instructors with support from various resources and adjusting the benefits offered according to their needs may also raise their motivation to persevere in their role. Moreover, health managers and educators should pay attention to and follow the professional training and guidance processes of new and existing clinical instructors to establish and strengthen their internal motivation so that they continue willingly in their positions.     

Non-self DNA on the neck: a 24 hours time-course study

Non-self DNA is normally present on skin due to DNA transfer occurring during daily activities. The understanding of persistence and accumulation of foreign DNA on the neck can assist in the interpretation of DNA evidence collected from an assaulted victim. Establishing the composition and level of non-self DNA present is relevant, especially in cases where the victim cohabits with other individuals, such as partner and children. This study investigated the persistence and accumulation of non-self DNA on the neck, over the course of 24 h. DNA samples were collected from the neck of 20 adult volunteers at three time-points, on two days. The detection of a partner's DNA and DNA from unknown sources was studied in relation to the living arrangement and to the activities performed by each individual. An increased number of non-self alleles were detected over time. Partner's DNA was observed to accumulate during the day and to persist when an individual was absent from the shared home environment. DNA from unknown contributors was found on the neck of individuals that used public transport, attended public spaces and had social interactions. The data acquired from this study will help to increase knowledge on the composition of DNA present on an individual's neck in a daily situation.     

Effect of machine-washing semen-stained fabrics on the persistence of human spermatozoa DNA: A systematic review of five articles

Biological evidence of sexual violence, such as semen, can change due to fabric washing. This can be due to attempts by the perpetrator to eliminate evidence or because the victim feels ashamed of sexual violence. While much research on this topic has been conducted, no systematic review has been attempted. This systematic review explores the effect of fabric machine-washing on the persistence of human spermatozoa deoxyribonucleic acid (DNA). This systematic review seeks in vitro experiments in which semen-stained fabrics were washed by washing machines, published in English, and matched with keywords in PubMed, Europe PMC, ScienceDirect, and Google Scholar. We then assessed the obtained articles with the Joanna Briggs Institute quasi-experimental checklist. This systematic review used the narrative synthesis method. Our search yielded five articles. These articles observe the effect of machine-washing factors on the persistence of human spermatozoa DNA, such as water temperature, washing duration, detergent type, washing repetition, and duration of fabric storage before washing. This systematic review shows that fabric washing insignificantly affects spermatozoa DNA persistence, and DNA might persist after multiple washes. However, variations in the articles indicate that future studies on this topic need to account for more variables and be reported in more detail to reduce bias.     

The persistence of seroprotective levels of antibodies after vaccination with PreHevbrio,a 3-antigen hepatitis B vaccine

Prevention of hepatitis B virus (HBV) infection by vaccination can potentially eliminate HBV-related diseases. PreHevbrio™/PreHevbri® is a 3-antigen (S, preS1, preS2) HBV vaccine (3A-HBV) recently licensed for adults in the US, EU and Canada. This study evaluated antibody persistence in a subset of fully vaccinated and seroprotected (anti-HBs ≥ 10 mIU/mL) Finnish participants from the phase 3 trial (PROTECT) of 3A-HBV versus single-antigen HBV vaccine (1A-HBV). 465/528 eligible subjects were enrolled (3A-HBV: 244; 1A-HBV: 221). Baseline characteristics were balanced. After 2.5 years, more 3A-HBV subjects remained seroprotected (88.1 % [95 %CI: 84.1,92.2]) versus 1A-HBV (72.4 % [95 %CI: 66.6,78.3)], p < 0.0001) and had higher mean anti-HBs [1382.9 mIU/mL (95 %CI: 1013.8,1751.9) versus 252.6 mIU/mL (95 %CI: 127.5,377.6), p < 0.0001]. In multiple variable logistic regression analysis including age, vaccine, initial vaccine response, sex and BMI, only higher post dose 3 (Day 196) antibody titers significantly reduced the odds of losing seroprotection.
